lM PROVEM ENT IN STRAW-CUTTERS.

Specification forming part of Letters Patent No. 56,428, dated July 17,1866.

To all whom it may concern:

Be it known that I, JOSEPH MAROHANT, of Cambridge City, Indiana, haveinvented certain new and useful Improvements in Straw- Outters; and Ihereby declare that the following is a full and clear description of thesame, reference being had to the accompanying drawings, and to theletters of reference marked therein.

Figure 1 is a perspective view of the cutting-box. Fig. 2 is a plan ofthe adjustable cam.

In Fig. 1, A is the balance-wheel, hung upon a cross-shaft of thecutting-box, constructed in the ordinary manner. B is a circularplatewheel attached to the same shaft as the balance-wheel A, having anelongated central opening, allowing it to slide between its center andcircumference upon its shaft or journal. O is the handle of athumb-screw, which passes through the slot of the cam or platewheel B,and is secured upon the inner face thereof by a cross-head, serving tohold the plate-wheel B in any desired position. The plate-wheel B has agroove in its circumferential surface, in which is fitted, workingloosely, one end of the rod E, the opposite end of which is attached tothe lower end of the rocker-shaft I, which is secured by a bolt to theframing X.

The pawls F and G operate the ratchetwheels H H, respectively, which areattached to the feed-rollers of the cutting-box.

D is a gravitating pawl, serving to hold the ratchet of the lowerfeed-roller in position.

By sliding the plate-Wheel farther from the center it lengthens thevibrations of the rockerarm and gives a greater motion to thefeedrollers, and a consequently longer cut of the straw, and thusconstitutes an adjustable cam.

By this arrangement I produce a simple, strong, and durable feedingdevice, which is easily adjustable, and working almost without friction.

Having thus fully described my said improvement, what I claim as myinvention, and desire to secure by Letters Patent, is-

The arrangement and combination of the balance-wheel A, adjustableplate-wheel B, thumb-screw G, rod E, pawls F and G, ratchetwheels H H,and rocker arm or shaft I, constructed and operating substantially asand for the purposes set forth.

JOSEPH MAROHANT.
